What it does Tennis Crosses string protectors lock and stabilize the strings on your racket to reduce string movement and extend string life. The raised nubs and textured surface give the ball more bite, helping produce increased spin and improved control. Compatibility Designed for use with badminton, tennis and squash rackets. Key benefits Longer string life: the protector reduces friction and lateral string movement, slowing wear. Better spin and control: the increased roughness and nubs on the protector help the ball grip the stringbed for more rotation and consistent ball flight. Portable and practical: compact design is easy to carry for practice, matches or travel. Easy installation: the included applicator tool lets you insert the protector quickly and securely, even with one hand. How it works The protector sits across the stringbed at the crossing points to lock adjacent strings and reduce movement. Its textured profile increases contact with the ball, transferring more spin while protecting strings from wear. Practical use scenarios Match play: add consistent topspin on serves and groundstrokes without changing string tension or setup. Practice and coaching: protect strings during repetitive drills to reduce frequent restringing and maintain predictable ball behavior. Travel and club sessions: carry a compact protector and applicator to quickly install between sessions for extended string life and improved control. What you get Tennis Crosses string protector designed for badminton, tennis and squash rackets, with an applicator tool for straightforward one-handed installation. This product is intended to protect strings, reduce string movement and enhance spin and control while remaining portable and easy to use.
